NAO-KICHI is a supporting character in Necronomico and the Cosmic Horror Show. He is a genius manga artist and an online influencer who built his reputation on a single acclaimed masterpiece. After that initial success, he was never able to publish another manga that satisfied his editors or resonated with audiences; every subsequent work was cancelled or poorly received. Having drawn manga since middle school, the craft is deeply important to him, and his stalled career weighs heavily on his mind.

Seeking fresh material for his next big hit, NAO-KICHI decides to participate in a mysterious virtual reality game called KADATH, hoping to spark new ideas. Outside of his professional struggles, he is described as down-to-earth and carries a genuine passion for caring for animals. His involvement in the VR game places him among the other streamers drawn into the Old Ones' deadly game show.

During the first VR game, NAO-KICHI is betrayed by a fellow player named Eita. The betrayal leads to his death within the game, and he loses his sanity as a result. His fate serves as a key early example of the high stakes and ruthless nature of the Cosmic Horror Show. NAO-KICHI does not appear to have any supernatural abilities; his strength lies in his creative talent and his popularity as an influencer, but those assets prove useless against the cosmic forces manipulating the game.
